SAE-Based Steering Cuts Whisper Hallucination Rate from 72% to 14%

June 4, 2026

Sparse AutoEncoder latents trained on Whisper encoder activations encode linearly separable hallucination signals, concentrated in deeper layers. SAE latent-space steering reduces hallucination rate from 72.63% to 14.11% on Whisper small without retraining the model.

HOW THIS AFFECTS YOU

●

builderYou can apply SAE-based activation steering to Whisper small in production to cut hallucination rates by ~58 percentage points without fine-tuning or model replacement.

●

researcherThe result demonstrates that SAE latents are more effective than raw activations for targeted behavioral steering, with strong quantitative support on a well-known failure mode.
